To ensure that your sender's reputation is kept intact at all times, we use a sophisticated verification process that can be triggered for your campaign if:
If this is your first email campaign in Omnisend.
If your last campaign was sent more than 90 days ago.
If the campaign you’re about to send goes to a 20% larger audience than any previous campaign.
If you upload a substantial number of new contacts to your Omnisend audience — especially when the number of new contacts represents a noticeable percentage of your existing list or past campaigns' audiences.
If your campaign is being verified, don’t worry—this process helps protect your sender's reputation.
Make sure your campaign sending has started. If you see any warnings, you’ll need to resolve them first.
How It Works:
When your campaign is being verified, we start by sending it to a small group of your contacts, about 1,000 recipients, regardless of the total number of contacts in your segment.
We monitor the results of this batch for one hour, checking metrics every two minutes. We check the reports of that batch to make sure it's safe to send it to the remaining part of your contacts. If the results stay within these limits, your campaign will continue sending automatically:
Bounce rate below 7%.
Spam complaints no more than 3.
Unsubscribe rate below 2.5%.
If the metrics look good, you don’t need to take any action—the rest of your campaign will be sent immediately.
In case of a high bounce or spam rate, we will ask you to review your contact list and unsubscribe old, inactive emails.
In case we notice any issues, we pause the campaign and inform you about it on the account. You can resolve the issues by going through a wizard that points out the reasons for the contacts being reported as inactive. The sending on your account will be temporarily paused until the issue is resolved. You may also reach out to our support team at any time if any assistance is needed.
The verification process itself takes 60 minutes. Our sending process is really quick, and once the verification is done, your campaign will go out within minutes.
If you tried sending a campaign and got a message saying that the email sending for your account was paused, our abuse-prevention system likely noticed something about your account or campaign that was not a usual case and needed additional attention.
